So found was sat in living room with my two cats they run off into kitchen to stare at the cupboard so I go through and open the cupboard cat jumps in and I hear something running away turns out there's a huge hole in the back of the cupboard that the cats couldn't get in. I've found some droppings, urgh. I've taped up the hole with black tape put flour down to see if they can still get out. And made a DIY mouse trap.... Feel so icky calling past man in morning
